The Tabletop Supercritical CO₂ Extractor is a tabletop supercritical CO₂ extraction system featuring one extraction vessel and two separation vessels. It uses CO₂ as the extraction medium, which is fully recyclable. The inner surfaces of all ships, pipelines, and valves that come into contact with biomass are made of 304 stainless steel, ensuring acid and alkali resistance and compliance with food-grade safety standards. The surfaces in contact with hot and cold water are also made of 304 stainless steel for enhanced durability.
The L-Series Tabletop CO₂ Extractor operates at a design pressure of 38 MPa and a maximum working pressure of 35 MPa. Engineers built the pressure vessel to last 20 years and followed Chinese design, manufacturing, inspection, installation, and commissioning standards.

BIT’s Tabletop CO₂ Cannabis Extractor – Five Key Features
BIT designed the tabletop CO₂ cannabis extractor for small-scale cannabis extraction, serving growers and small businesses. With its portable and compact design, it is ideal for space-limited environments. Moreover, the system compresses and liquefies CO₂ gas, and then uses it as a solvent to extract valuable compounds from cannabis plants, ensuring efficiency and high-purity results.
• Compact & Portable – Lightweight and easy to transport, fitting on a laboratory bench or small workspace.
• Built-in Temperature & Pressure Gauges – Enables precise adjustments via a PLC touchscreen, ensuring consistent extraction results.
• Automated Operation – Prevents under-extraction and over-extraction, ensuring batch-to-batch consistency.
• Advanced Safety Features – Equipped with built-in pressure relief valves and automatic shutdown when pressure or temperature exceeds limits, ensuring operator safety and preventing equipment damage.
• High-Quality Extracts – Through precise temperature and pressure control, the system produces high-terpene, cannabinoid, and flavonoid-rich cannabis oil, free of solvent residues or contaminants.
